Having talked to Matt about his TBs, he's pretty spot on with his choices when it comes to size selection based on mods.

Ah, headers. That makes perfect sense.

There is only 1 reason you should not be getting the Biggest Baddest Ported throttle body for your truck.

Because someone who has not tried one tells you too.LOLOLOL.

The 4G motor is just short of a race motor,it is a high compression tricked out motor ,that was detuned for emissions sake.

If you think the motor will not benifit from Non OEM parts then please dont continue to read this post.

I would recommend anyone planning to add a CAI,or just want a little better MPG or performance should get the biggest Thottlebody they can find up to and including a 87MM model.

To say a 87MM throtlebody will not show a big improvement in throttle response and in performance is just crazy talk.
Maybe not so much in a say a Ford or Chevy v-8,but the Hemi motor is not even in the same ballpark.

I would be happy to swap out my 87MM Moes throtllebody into CdnilRams truck,we could do some 0-60 tuner tests,and some MPG testing.
Surely a real world test would benifit everyone looking at this mod.

Im surprised Matt at Moes can even keep these on the shelf.
I have know Matt for a long time,he is all about performance,hes not about selling something that does not live up to his expectations.
Thanks for a great product Matt.

This doesnt have to be a pissing match here,but the information posted here is rediculous.and I think everyone would benifit from some real world testing.

Heres my number.
Grant 403-617-8733.
Name the weekend and lets do some testing.
Im sure Steve at Davenport Motorsports would let us do a before and after test on your truck as well.

Actually Grant, after talking with Matt about all this and my build, he agrees that his 87mm wouldn't be a good thing on my truck and the 90mm that I have is the best option. With the volume demands my new engine has, the constriction of the 80mm butterfly would not be a good choice as it would choke out the motor starting in the mid-range.

Here's some of the PMs he sent me on another forum:

Quote:
For the wild build you are planning, there is no doubt that a 90mm TB is in order. 95% of guys on the forums stick to the basic boltons and a mild cam, and that is exactly the build that we designed these TB's for. I would like to get another truck on the dyno to try both the 85mm and 87mm compared to stock, but the seat of the pants gains from the guys running these has been great. I appreciate yo utaking the time to hear me out on this. Good luck with your build. I'm excited to see how it goes.

BTW...we just came out with our 2013 TB's now as well. We tested these in both the 85mm and 87mm design, and the 87mm actually performed better, even on a bone stock truck. We just finished our first production run of them, so I will be posting pics of these later. I have a few on the way to customers now, so we should see some feedback from them sometime next week. None of the 2013's are modded yet, so this should be a true test as to whether they work or not. Our test truck dropped .15 at the track with the TB alone, so I'm expecting good things once the guys start running them.

Take care.

Matt
Quote:
Thanks. The info was good in the original, but I think the way it was worded was just over most peoples head, so it was taken in a different way than you intended. In all honesty, aside from the guys with boost, a ported stock TB like the 87 is more than enough for most guys. The straight bore TB's from BBK and Arrington are nice because they flow more air, but with less airspeed. Better to pend power, loss of tq. Having said that, boosted guys arent too worried about losing a few tq down low, so it is a good compromise. On a bolt-on, or even mild heads/cam truck, the 87 has proven to be the way to go.
So, you can see that Matt and I agree on the need for intake velocity to increase/maintain torque. He even states that there are limitations to his TBs on bigger builds, which you will see I talk about in the end of the original post. Matt and I are on the same page and I still recommend his and fastman's ported TBs if they suit a person's build.

Though, if you are serious about the offer, I would love to prove the point when I get it all put together and onto the dyno at Davenport. I could honestly show the difference between a bone stock, ported 87mm, true 85mm, and a true 90mm on an engine that's built to flow volume. We've already seen the benefits of flowing a higher velocity on a stock and mildly modded engine, and I am genuinely interested to see how it would affect the torque and hp curves, just making the change to the volumetric flow rate.

For others, here's a good reference table from another forum that is quite accurate. I have bolded the 5.7L's stats.

Using the chart is simple. If peak power is higher than the rpm in the 1.2 “/Hg column, or peak torque is higher than the rpm in the 0.8”/Hg column, then you should really consider an upgrade. If peak power is higher than the rpm in the 0.8”/Hg column, or your shift point is is higher than the rpm in the 1.2”.Hg, an upgrade can be of benefit in an “max-effort” application, but isn’t absolutely necessary. I even included accompanying power outputs, so you can also make a selection based off of expected N/A power.

Throttle Body Selection Chart
-----------80mm ----------85mm ---------90mm
---------0.8-1.2"/Hg ----0.8-1.2"/Hg ----0.8-1.2"/Hg
345___5190-6360_____5920-7250____6700-8200
370_____4840-5930_____5520-6760_____6250-7650
392_____4570-5590_____5210-6380_____5900-7220
426_____4200-5150_____4790-5870_____5420-6640
440_____4070-4980_____4640-5680_____5250-6430

I dont think the 90MM throttle body will work without throwing codes but Im sure you will find out.
Im sure we can get something figured out with Davenport let me know.
Let me know if you need a hand.

I put an 85mm on my Challenger and noticed great throttle response improvement. (other mods are LMI CAI, Flowmaster cat back and Diablo custom tune).
Dyno indicated about 4-5 ft lbs gained (when Tb was the ONLY addition) but that is throughout the low and mid-range which is where I wanted more power as that's where we drive the most...once I could tune it the guy that did my custom tune said that it was VERY beneficial and on a 392 he would suggest the ported 87mm but I didn't spring for the extra expense again for +2mm porting.

I plan to run whatever Matt suggests on my 2013 Sport CC 4x4 if Ram ever gets around to building it for me...ha. Probably the 87mm and an S&B intake.

I've been contemplating running my BBK 85mm for a while and holding onto the 90mm until I start running higher boost. For the 8-9psi a 90mm might be overkill, but I'll keep it just to have options. My engine won't like me either way, thank god for guys like Johan that can beat it into submission.

Once you go boost you can switch back to a stock throttle body and sell the larger one to get some money back. It won't be the restriction any more.
